The first proven record of this species was in 2024 at WV.
Invasive
The eggs are white with brown spots.
The female lays the eggs while sitting on grasses, but this often also happens in flight. Hibernates as a young larva. Pupation takes place in a cocoon in a sheltered place or in a hole in the ground. The adults rarely rest with open wings and have a habit of resting on the trunks of trees. Its flight is more gliding than fluttering.
Adults are on the wing between June and September, occasionally later.
The larva feeds on different species of Poaceae like Bromus erectus.
It inhabits open grasslands with scattered trees, steppes, open scrubland, and open woodland areas.
